Intern. Med. 69: 919, 1968).They purport to show the advantage of isopotential mapping over electrocardiography and vectorcardiography, but they fail to show any electrocardiograms for comparison and only one vectorcardiogram.Although the two single QRS complexes in Figure 1 were similar, they were not identical; the complex in the case of the right ventricular hypertrophy (RVH) had an R:S ratio of nearly 1, one of the electrocardiographic criteria for RVH (1).

Major Body Burn
Authors: Curtis P. Artz
Journal: JAMA (1973)

Major burns have been a serious problem in the United States for many years. According to the National Health Survey for the years 1957 to 1961 there are 1,973,000 injuries annually. Of these, 268,000 require bed care. Statistics compiled by the US Department of Health, Education, and Welfare for the year 1960 show that there were 7,645 deaths due to accidents resulting from fire and explosion. The death rate during this period was 4.3/100,000 population.<sup>1</sup> <h3>Causes.—</h3> Thermal burns most commonly result from contact with hot liquids or metals, explosions (flash burns), or flames. Scald burns are most common in children under 3 years of age. They frequently result from bathtub accidents or the overturning of containers of hot liquids by inquisitive youngsters. In the 3- to 15-year age group, major burns usually result from the misuse of fire or matches. The ignition of clothing from open fires and heaters
The Distribution of Euthyroid Serum Protein-Bound Iodine Levels
Authors: Jerald C. Nelson
Journal: JAMA (1971)

The dispersion of serum protein-bound iodine levels in euthyroid subjects does not allow a normal curve of distribution. Therefore, the mean ± 2 standard deviations does not define the central 95% of a "normal" population for this test. The logarithmic transformation provides a reasonably good fit to the normal distribution curve and allows the calculation of the central 95% of the values. In this study the limits of the central 95% of values were 3.4 to 8.2μg/100 ml.

Hazards of Snuff
Authors: Arthur W. Weaver
Journal: JAMA (1973)

<h3>To the Editor.—</h3> I was interested to read Dr. James Smith's comments (224:1763, 1973) disputing Dr. George Moore's assertion that snuff is hazardous (223:336, 1973). Dr. Smith's statistics are impressive! Even more impressive, however, are patients<i>with</i>cancer developing in the quid site. We, personally, have seen two in the past month. These precancerous changes (Fig 1) and frank malignant neoplasms (Fig 2) are so specific that the cause can be surmised before a history of snuff use is elicited.

Liver Posters
Journal: Gut (2001)

Results:The mean age of the patients (65 males; 75 females) was 66 years (range = 27-96).The rate of cannulation of the duct of interest was 127 out of 140 cases (91%), and both endoscopists and radiologist's reports were available in 118 of these. Conclusion:The role of radiologists' interpretation of postprocedure ERCP spot films is small but significant.We believe this procedure should continue but be subject to further review.
Black Student Enrollment in US Medical Schools
Authors: Sterling M. Lloyd
Journal: JAMA (1989)

Blacks represent about 12% of the nation's population, but only 6% of the total medical school enrollment, 5% of medical school graduates, 5% of postgraduate trainees, 3% of physicians in practice, and 2% of medical school faculties. Addressing this underrepresentation of blacks in medicine not only is a matter of justice, equity, and national conscience but also has implications for the provision of quality physician care to this nation's minority and medically underserved populations. Black physicians are more likely to understand the cultural and social context of illness and disability among blacks and are also more likely to be able to communicate effectively with black patients. Black physicians are also more likely to practice in communities whose residents lack adequate access to medical care. An approach to addressing the problem of underrepresentation is proposed, consisting of activities at the precollege, college, and medical school levels. (<i>JAMA</i>1989;261:272-274)
Cost of a Home Parenteral Nutrition Program
Authors: Leon P. Wateska
Journal: JAMA (1980)

We analyzed the costs to a hospital of providing complete home parenteral nutrition (HPN) services for eight patients. Identified cost components include patient training, equipment, supplies, and follow-up. The average annual cost of maintaining parenteral nutrition at home was 73% lower than it would have been in the hospital. The establishment of private companies to provide patients with HPN supplies and services will reduce the financial burden of HPN programs for hospitals. (<i>JAMA</i>244:2303-2304, 1980)
Committee to Be Named to Advise Government About Fetal Tissue Transplantation Experiments
Authors: Charles Marwick
Journal: JAMA (1988)

THE DEPARTMENT OF HEALTH and Human Services (DHHS) is putting transplantation of fetal tissue on hold pending review by an outside advisory committee of ethical and legal questions that the procedure raises. Apart from one already funded study, the federal government will not support clinical studies using fetal tissues until the committee has made its report. A selection group will nominate approximately 20 persons for the advisory committee and James B. Wyngaarden, MD, director of the National Institutes of Health (NIH), will make the appointments. The single study allowed to continue is a $150 000 project that involves implanting fetal pancreatic tissue for juvenile diabetes. Since it had already been funded, it would not have been legal to stop it. Nevertheless, the principal investigator, Hans Sollinger, MD, University of Wisconsin, Madison, has decided not to proceed with the human studies until the committee makes its report.

Pregnancy and the Timing of Intercourse
Authors: Joe Leigh Simpson
Journal: New England Journal of Medicine (1995)

The optimal timing of sexual intercourse in relation to the day of ovulation in order for pregnancy to result is a topic of broad interest. Of obvious relevance to fecundability, on the one hand, and contraception, on the other, the timing of intercourse also bears on the possibility of altering the sex ratio among infants and on the pathogenesis of chromosomal abnormalities. Unfortunately, the evidence has been contradictory because of the inadequacy of methods for detecting ovulation, estimating the timing of conception, diagnosing early pregnancy, and assessing outcomes. The study reported on by Wilcox et al. in this issue of . . .
Deaths Associated With Hurricane Georges--Puerto Rico, September 1998
Journal: JAMA (1998)

On the evening of September 21, 1998, Hurricane Georges struck Puerto Rico with estimated maximum winds of 115 mph (Category 3). It made multiple landfalls throughout the Caribbean, including Antigua, the U.S. Virgin Islands, Hispaniola, and Cuba. On September 25, Hurricane Georges struck the U.S. mainland near Key West, Florida, and made final landfall on September 27 in Biloxi, Mississippi, as a Category 2 hurricane. This report presents preliminary data about deaths resulting from the hurricane in Puerto Rico.

In<i>situ</i>evidence that the population of Langerhans cells in normal human epidermis may be heterogeneous
Authors: B. SONDELL, M. JONSSON, P. DYBERG, T. EGELRUD
Journal: British Journal of Dermatology (1997)

Epidermal Langerhans cells (LC) may occur in subsets with different phenotypic and functional characteristics. In this work we give further evidence that the CDla-positive LC population in the normal human epidermis may be heterogeneous. We found that one of our monoclonal antibodies (TE4B) to stratum corneum chymotryptic enzyme (SCCE) stained a population of dendritic cells in the normal epidermis, in addition to high suprabasal keratinocytes. The staining of the dendritic cells was seen only when the biopsies had been fixed with formaldehyde and when the sections had been pretreated, either with proteolytic enzymes or with Triton X-100. The blinding of the antibody was mediated through its antigen binding site, as it could be inhibited by adsorption with recombinant pro-SCCE. Experiments with double labelling showed that the TE4B-positive dendritic cells were also CDla-positive. On the other hand, not all CDla-positive cells were TE4B-positive. By means of confocal microscopy of double-labelled cells, the TE4B binding site could be localized intracellularly. SCCE-mRNA could be detected by in situ hybridization in high suprabasal keratinocytes only. A possible explanation may be that there is a subset of LC which have taken up SCCE secreted by high suprabasal keratinocytes. Alternatively. TE4B may bind to an epitope present in a subgroup of epidermal LC which cross-reacts immunologically with SCCE. It is suggested that the demonstrated heterogeneity of the population of LC in the normal epidermis should be taken into account in studies on the possible role of epidermal autoantigens in the development of immune-mediated skin diseases.

Does interferon therapy for chronic hepatitis B reduce the risks of developing cirrhosis and hepatocellular carcinoma?
Authors: Anna S. F. Lok
Journal: Hepatology (1995)

Objective: To estimate the cost-effectiveness of interferon-α2B for the treatment of patients with chronic hepatitis B infection who are positive for hepatitis B e antigen (HBeAg). Design: Meta-analysis of nine randomized controlled trials and cost-effectiveness analysis, projecting the clinical and economic outcomes expected from changes in serologic markers of hepatitis B viral replication. Data Sources: MEDLINE search, expert panel opinion, hospital cost data, and adjusted physician charges. Patients: 552 patients with confirmed chronic hepatitis B infection who were positive for HBeAg. Intervention: Interferon-α2b. Measurements: Lifetime incidence of cirrhosis and hepatocellular carcinoma; life expectancy; quality-adjusted life expectancy; and costs and marginal cost-effectiveness ratios from a societal perspective. Results: Interferon-α2b increases the likelihood of becoming negative for HBeAg from 9.1% to 45.6% (difference, 36.5%; 95% CI, 23.7% to 49.2%) and of becoming negative for hepatitis B surface antigen from 1.7% to 7.7% (difference, 6.0%; CI, 2.8% to 9.3%) in the first year. For a 35-year-old person with chronic hepatitis B who is HBeAg positive, our analysis suggests that interferono; α2b will increase life expectancy by 3.1 years or 3.4 quality-adjusted life-years and will decrease projected lifetime costs, even if future savings are discounted; thus, interferon-α2b is the dominant strategy. Even with the model biased strongly in favor of standard care, the marginal cost-effectiveness ratio of interferon did not exceed $12 000 per life-year gained. Conclusions: Interferon-α2b should prolong life and lower costs for patients with chronic hepatitis B who are HBeAg positive.
Variations in Resource Utilization Among Medical Specialties and Systems of Care
Authors: Sheldon Greenfield
Journal: JAMA (1992)

<h3>Objective.</h3> —To examine whether specialty and system of care exert independent effects on resource utilization. <h3>Study Design.</h3> —Cross-sectional analysis of just over 20 000 patients (≥18 years of age) who visited providers' offices during 9-day periods in 1986. Patient- and physician-provided information was obtained by self-administered questionnaires. <h3>Setting.</h3> —Offices of 349 physicians practicing family medicine, internal medicine, endocrinology, and cardiology within health maintenance organizations, large multispecialty groups, and solo practices or small single-specialty group practices in three major US cities. <h3>Outcome Measures.</h3> —Indicators of the intensity of resource utilization were examined among four medical specialties (family practice, general internal medicine, cardiology, and endocrinology) and five systems of care (health maintenance organization, multispecialty group—fee-for-service, multispecialty group—prepaid; solo practice and single-specialty group—fee-for-service, and solo practice and single-specialty group—prepaid) before and after controlling for the mix of patients seen in these offices. The indicators of resource utilization were hospitalizations, annual office visits, prescription drugs, and common tests and procedures, with rates estimated on both a per-visit and per-year basis. <h3>Results.</h3> —Variation in patient mix was a major determinant of the large variations in resource use. However, increased utilization was also independently related to specialty (cardiology and endocrinology), fee-for-service payment plan, and solo and single-specialty group practice arrangements. After adjusting for patient mix, solo practice/single-specialty groups—fee-for-service had 41% more hospitalizations than health maintenance organizations. General internists had utilization rates somewhat greater than family physicians on some indicators. <h3>Conclusion.</h3> —Although variations in patient mix should be a major determinant of variations in resource use, the independent effects of specialty training, payment system, and practice organization on utilization rates need further explication. The 2- and 4-year outcomes now being analyzed will provide information critical to interpretation of the variations reported herein. (<i>JAMA</i>. 1992;267:1624-1630)
Recognition of Impending Ketoacidosis Delayed by Ketone Reagent Strip Failure
Authors: Arlan L. Rosenbloom
Journal: JAMA (1978)

During a one-year period, six patients were admitted to the hospital in diabetic ketoacidosis following 12 to 24 hours of illness at home. Urine testing with strips impregnated with sodium nitroprusside had indicated that no ketone bodies were present. Nine of 11 bottles of reagent strips in use for less than three months by these and other patients contained totally unreactive strips. Nitroprusside tablets exposed more than three months continued to give accurate readings. (<i>JAMA</i>240:2462-2464, 1978)
